2023年11月3日 · Fibularis tertius is a muscle of the anterior calf whose function is to dorsiflex the foot. Learn everything about its anatomy and function at Kenhub!

In human anatomy, the fibularis tertius (also known as the peroneus tertius) is a muscle in the anterior compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body and to pull the foot upward toward the body (dorsiflexion).

Fibularis Tertius Syndrome is a condition characterized by catching, clicking, locking or popping of peroneus tertius tendon over ankle during walking. It is a rare condition of anterolateral ankle pain or rear foot pain.

2023年1月7日 · The fibularis tertius is a muscle in the anterior compartment of the leg. It is an extension of the distal part of the extensor digitorum longus muscle and is not always present. Attachments: Originates with the extensor digitorum longus from the medial surface of the fibula.

Origin: Medial surface of fibula and adjacent interosseous membrane of leg. Insertion: Dorsal aspect of base and body of fifth metatarsal bone. Action: Dorsiflexes foot at ankle joint; assists in eversion of foot at subtalar and transverse tarsal joints. Innervation: Deep fibular nerve (L5-S1).

2023年1月2日 · The peroneus tertius (fibularis tertius) is one of the muscles within the anterior compartment of the leg. Collectively, the muscles of the anterior compartment act to extend the toes, dorsiflex the ankle and invert the foot.

The fibularis tertius muscle (FTM) is a rare anatomic variation. The prevalence of this exclusively human structure, which is found in the anterior compartment of the leg, is often underestimated, and it is believed that foot and ankle conditions are more difficult to …

2021年8月2日 · Fibularis tertius The peroneus tertius muscle, also known as fibularis tertius muscle, is a muscle of the anterior compartment of the leg, despite its name suggesting it is in the lateral compartment. It aids in dorsiflexion and eversion of the foot. On this page: Article: Summary; Gross anatomy ...

The Fibularis Tertius muscle, with its unique origin, insertion, muscle path, and function, plays a crucial role in the intricate system of muscles responsible for lower leg and foot movements. Its actions are essential for maintaining balance, stability, and efficient locomotion.

Being considered an exclusive human structure for a long time, fibularis tertius (FT) is believed to have a secondary function of foot dorsiflexion and eversion. This study is an attempt to approach the issue from an anatomical perspective.
